5.2 Types of work
WARNING
Risk of electric shock! Severe injury and burns can result if any attempt
is made to operate the tool without an earth/ground conductor and ground
fault circuit interrupter correctly connected.
▶ Irrespective of whether mains power or generator power is used, always
make sure that an earth/ground conductor and ground fault circuit
interrupter are present in the power supply and that these are correctly
connected.
▶ Do not use the product unless these safety measures are in place and
fully operational.
WARNING
A damaged supply cord presents a hazard! If the supply cord or extension
cord is damaged while work is in progress, immediately disconnect the
device and the cord from the electricity supply. Do not touch the damaged
part of the cord.
▶ Regularly check all supply cords. Replace defective extension cords.
Full approval must be obtained from the site engineer or architect prior to
beginning the work.
5.2.1 Drilling without hammering
Drilling without hammering is possible when drill bits with a special
connection end are used. Tools of this kind are available from the Hilti
tools range.
For example, when the keyless quick-release chuck is fitted, smooth-
shank drill bits for wood or steel can be used to drill without hammering.
▶ Set the function selector switch to the
5.2.2 Drilling with hammering action (hammer drilling)
▶ Set the function selector switch to the
5.2.3 Chisel positioning
CAUTION
Risk of injury! Loss of control over the chisel direction.
▶ Do not operate the tool when the selector switch is set to "Chisel
positioning". Turn the function selector switch until it engages in the
"Chiseling" position.
The chisel can be set to 24 different positions (in 15° increments). This
ensures that flat chisels and shaped chisels can always be set to the
optimum working position.
